I originally posted this to Meta Stack Exchange and was told that it should be here instead.

I reviewed a post in the Super User First Post queue and thought it sounded familiar. I searched for the subject and found a previous post with the same question. I then added a comment recommending they search for previous questions and gave them a link to the duplicate question and answers. Since the audit changed the name of the user, there was no way for me to know otherwise. So why would I fail then?
